  Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of the chemical compound butadiene with hydroxyl functional groups completed at the individual end. Polyurethane polymers are produced with the reaction of hydroxyl-terminated polybutadiene with   isocyanates . It is a translucent liquid with a color similar to that of wax paper and viscosity texture as corn syrup. The major application area for the HTPB compounds is solid rocket propellant. Due to the properties such as excellent hydrophobicity, low glass transition temperatures and low volatiles content, these polybutadienes are used majorly in aerospace and defense industries. Environmental Protection Agency (EPA): All components of HTPB are listed or excluded from listing on the United States Environmental Protection Agency Toxic Substances Control Act (TSCA) inventory. This product contains no toxic chemicals in excess of the applicable de minimis concentration subject to the reporting requirements of Section 313 o...

  Hydroxyl Terminated Polybutadiene (HTPB) is the most commonly used   polyol   in recent times. Due to its excellent physical properties, such as high tensile and tear strength and good chemical resistance possessed by this chemical, it acts as a fuel binder for PU propellant. The chemical HTPB contains hydrogen and carbon as its main constituents during combustion. It becomes chemically and physically compatible with conventional oxidizers and other ingredients.
